Before starting a project you need a clear market analysis to check if there is a viable market for such a item, and some scope of the related costs for R+D and production and time frame for launch. Have you done a market study on the current state of Polaroid films such as through the impossible project, or fuji instax products, or the Zink printer makers? You need to research and have a clear understanding of their technology and related products, and their delivery of these products to whatever market segment they aimed for.

Also I dont think kickstarter allows projects anymore without a prototype as lots of people were scammed when nifty videos were made and companies did not deliver on their products.
